Really nice shifts in the movements of each elements. I love how the initial concepts (slight movements in each of the three sections) seem like the core of the final idea and how you switched from a photograph to very specific graphics. Really great work and thanks for sharing!

Just a quick comment on Slack. It's somewhat difficult to get people /companies to use Slack unless they see its value right away. We've tried to use it in our company and it hasn't take off. Email will stick around for a while, and Slack serves a slightly different purpose.
